Protect your microphone with Oticon O-Cap & T-Cap Microphone Filters

The microphone in your hearing aid is in a vulnerable position when it comes to protecting your hearing aid. When the microphone is exposed to dirt and debris from your ears and surroundings, it can damage the sound quality. That’s why it’s a good idea to use an Oticon O-Cap or T-Cap microphone filter to protect the microphone input. The filters shield the microphone from dirt, moisture, and earwax, which can affect the sound of your hearing aid. By regularly replacing the filters, you ensure that you always receive good and flawless sound, and you reduce the number of repairs to your hearing aid.

Oticon O-Cap is a microphone filter for newer Oticon in-the-ear hearing aids. The filter is nano-coated and designed to prevent foreign objects from entering the microphone input, which is one of the most common causes of malfunctions in in-the-ear hearing aids. Oticon T-Cap is a microphone filter for Oticon IIC hearing aids and Oticon CIC hearing aids, which shield your hearing aid from harmful particles. The sound remains clean and clear when the microphone input is protected by the filter. The T-Cap filter is nano-coated and designed to prevent debris from settling in the microphone.

It is recommended to change the O-Cap and T-Cap filters at least every 6 to 8 weeks, or more frequently if you are in dusty or dirty environments, to achieve the best possible sound quality. If the filters are blocked, they need to be replaced. You can choose the color that matches your hearing aid.

Replacing the microphone filter

When your hearing aids are exposed to dust, you may notice changes in the sound. If you experience difficulties in communication and the sound quality becomes less sharp than usual, it’s time to replace your microphone filters. Sound directionality may also become more challenging, and in general, the sound from your hearing aids becomes less clear when the microphone filters need to be changed. Therefore, it is recommended to replace the microphone filters regularly, at least every 6 to 8 weeks.

Regular replacement of the microphone filters protects your hearing aids from dirt and moisture, which can affect the sound in your hearing aid. This ensures that the sound quality is always at the same level as when you purchased your hearing aids. It is very easy to replace the microphone filter with the small tool provided when you order a microphone filter.
